Improvement in harvesters



JAMES PINE, OF TROY, NEW YORK.

IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 112,506, dated April 26, 1864.

To all whom it may concern: i

Be it known that I, JAMES PINE, of Troy, in the county of Rensselaer and State ot' New York, have invented a new and Improved Grain and Grass Harvester; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lis a front View of my invention, partly in section, asindicated byline w x, Fig. 2. Fig. 2 is a plan or top view of the same, partly in section.

Similar letters of reference indicate corresponding parts in the two figures.

This invention has for its object the diminution of side draft, simplicity of construction, and lightness, withv a requisite degree of strength.

The invention consists in the employment or use of two driving-wheels, arranged in a novel manner, and with a main frame and double-jointed linger-bar, as herein set forth.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the main frame of the machine, which may be of metal-that at least is the material designed to be used; and Bis one of the driving-wheels, the axle a of which is at the front part of the frame A, at the left-hand side of same, and has a concentric toothed rim, b, at its inner side.

At the back part of the main frame A there is a shaft, C, having at one end a pinion, D, which gears into the toothed rim b. This pinion I) is connected to the shaft G by a pawland-ratchet arrangement, (shown at c in Fig. 2,) so as to admit of the shaft being rotated when the machine is drawn forward, but not when the machine is backed. y

At the back end of the frame A, at its righthand side, the axle d of the driving-wheel D is placed. This wheelD isconsiderably smaller than the wheel B,and it has a concentric toothed rim, c, at its inner side, into which a pinion, E, gears, the latter being on the shaft C at the end opposite to that where the pinion D is placed. This pinion E is connected with the shaft C by means of a ratchet-and-pawl arrangement, c', which, as well as that c of the pinion D, is old and well known, and therefore does not require a special description. By this arrangement it will be seen that both driving-wheels B D are lmade to rotate the shaft C, from which motion is communicated to the sickle, as herein set forth.

F represents a bar, one end of which is counected by a joint,f, with a pendant, g, at the front part of the main frame A, where the axle c ofthe driving-wheel B is attached. To the lower part of the pendant g there are attached two bearings, It h, in which a short shaft, G, is fitted and allowed to rotate freely. This shaft G has a beveled pinion, t', on its back end, into which a bevel-wheel,H, on the shaft (l gears when the machine is in operation. The wheel H is allowed to slide on the shaft C, and the former may be moved by any suitable lever arrangement, so that it may be thrown in and out of gear with the bevelpin ion t. The sickleis operated from the front end of the shaft G bymeans ofa crank and pitman arranged in the usual way. The'barF, at its outer end, is connected by a joint, j, with a shoe, I, which rests upon the ground, and has the finger-bar J attached to it. This ringerbar, as well as the sickle, may be constructed and arranged in the same way as those in common use. The pendant g is directly below the axle a, and hence it will be seen that the bar F and cutterbar J are within the plane of the larger or main driving-Wheel B, extending at about right 'angles therefrom, and directly in front of the small drivingwheel D. The bar F is braced by a rod, K, from the back end of the frame A. Thus by this simple arrangement I avoid side draft and obtain a doublejointed finger-bar in line with the axle a of the main driving-wheel B, so that the iinger-bar may rise and fall at either end or horizontally to conform tothe inequalities of surface over which it may pass.

I do not claim a double-jointed linger-bar, for that has been previously used; but,

Having thus described my invention, what I do claim as new, and desire to secure by Letters Patent, is

l. The two driving-wheels B D, of different diameters, connected with the main frame A,

:is shown, and connected by suitable gearing driving-wheel B D tnd the frame A, all oonwith a. shaft, G, on said freine, substantially struoted and arranged in the manner and for 4 as and for the purpose herein set forth. the purposes set forth.

3. The bar F and finger-bar J, connected JAMES PINE. together by ajoint,j, as shown, and the for- Witnesses: mer attached to the pendant g ofthe frame A J. ROMEYN, by a joint, f, in combination With the two J. U. PECK.
